利用车载GPS轨迹数据实现公交车驾驶安全性分析

目的 交通拥挤在高度城市化地区正在成为一个日益严重的问题,而造成拥堵的原因之一就是由于一些不安全驾驶行为所带来的交通事故。因此,准确评价驾驶员的驾驶行为是否安全成为研究的热点。提出了一种利用车载GPS模块采集的车辆轨迹数据实现车辆驾驶行为安全性分析的方法,试图自轨迹数据中提取超速、急加速、急减速、急转弯这些潜在的不安全驾驶行为,进而评估驾驶行为的安全性,为交通管理部门评价和管理驾驶员的驾驶行为提供科学的依据。由于实验数据来自于公交车辆,因此,以公交车驾驶行为为潜在的研究对象。

Driving Behavior Analysis Based on Trajectory Data Collected withVehicle-mounted GPS Receivers

Objective Traffic congestion is becoming an increasingly serious problem in highly urbanized areas.One reason for congestion are frequent happened traffic accidents caused by risky driving behaviors.The accurate evaluation of a driver behavior as well as safety analysis has therefore become a researchhotspot.In this paper,a new method of using the vehicle-mounted GPS model to collect the vehicletrack data and analyzing the safety of driver’s behavior is presented.In the approach,information aboutdriving over the speed limit,quick acceleration,sharp slowdown and sharp turns is extracted from the trajec-tory data.Then,the security of a drivers’behavior assessed to provide scientific evidence for the trans-portation department managers when evaluating and managing a drivers’driving skill.
